xcode XCTest，无法加载测试包。测试启动时崩溃

XCTest, Failed to load test bundle. Crash on test launch

提问by Andy Obusek

In Xcode 9.1, I added a Unit Test Target to an older project and I'm not able to get tests to run. The target crashes on launch with the following error in the console:

在 Xcode 9.1 中，我向旧项目添加了单元测试目标，但无法运行测试。目标在启动时崩溃，控制台中出现以下错误：

The bundle “XXXTests” couldn't be loaded because it doesn't contain a version for the current architecture*

无法加载包“XXXTests”，因为它不包含当前架构的版本*

Stuff I've checked after extensively googling:

我在广泛谷歌搜索后检查过的东西：

• Build Active Architecture Onlysetting is consistent across the app and test targets (With a value of Yes)
• Enable Testabilityis set to Yes for the main target
• I've deleted the target and started over, no luck

• Build Active Architecture Only设置在应用程序和测试目标之间保持一致（值为 Yes）
• 主要目标的“启用可测试性”设置为“是”
• 我已经删除了目标并重新开始，没有运气

How do I fix this?

我该如何解决？

Make sure iOS Deployment targetfields of your application target and test target are the same

确保iOS Deployment target您的应用程序目标和测试目标的字段相同

I had the same issue. Simply building and running the associated application target on an iOS11.1 simulator (which happens to match the "iOS Deployment Target" of Test target) it started working.

我遇到过同样的问题。只需在 iOS11.1 模拟器（恰好与测试目标的“iOS 部署目标”匹配）上构建和运行关联的应用程序目标，它就可以开始工作了。

It seems starting the test the first time did not trigger a build of the test host. Subsequent runs seem to trigger the builds as needed and all is good.

第一次开始测试似乎没有触发测试主机的构建。随后的运行似乎会根据需要触发构建，一切都很好。

YMMV

It happened to me when updating the Xcode version from 9.3 to 10. In my case, deleted the DerivedData, then the unit test works.

我在将 Xcode 版本从 9.3 更新到 10 时发生了这种情况。在我的情况下，删除了 DerivedData，然后单元测试工作。

I had the same error. And for me what it worked was the following:

我有同样的错误。对我来说，它的作用如下：

• Select your test on the PROJECT NAVIGATOR
• on the right side, in FILE INSPECTOR choose the Target Membership, in this case your test target.

• 在项目导航器上选择您的测试
• 在右侧，在 FILE INSPECTOR 中选择Target Membership，在本例中为您的测试目标。

In my case, I had Macversion of OCMock.frameworkedin Link Binary with Librariesbuild phrase for an iOSproject.

就我而言，我的Mac版本OCMock.frameworked在Link Binary with Libraries构建短语的iOS的项目。

Removing it solved the issue for me.

删除它为我解决了这个问题。
